Magnification

This article lists ways to improve ergonomics that include magnification (loupes and intraoral cameras), operator seating, hand instruments, and gloves. Loupes can help hygienists in reducing injuries and keep good posture by magnifying and providing better view and angle of the patient s mouth. Studies have shown that loupes help reduce pain in back and neck. Intraoral cameras, like loupes, also improves visibility of the mouth by magnification, allowing hygienists to improve ergonomics and…

Burris MTAC: Quality Battlefield Optic on a Budget Nestled in at the base of the majestic Rocky Mountains, Greeley Colorado is home to Burris Optics. Following a twelve-year tenure with Redfield Optics where he pioneered numerous innovations including the first constantly centered non-magnifying reticle scopes, Don Burris set out to make a name for himself. Beginning in 1971, Burris introduced his own line of scopes including the original Fullfield released in 1975, compact handgun scopes in…

food’s characteristics can be GM to become a vehicle for vaccines and a higher vitamin content, slowing the spread of diseases and thus improving human health. Furthermore, plants that are GM to be pest-resistant will cause a decrease in biological magnification. Finally, plants with increased tolerance to the environment will ensure a sustainable and reliable food supply. As genetic engineering involves altering the genetic structure of a plant, it creates a controversial issue; however, Nina…

“lenses” over an object it would make the object appear larger. They referred to these early glass pieces as magnifiers or like mentioned earlier burning glasses. During this same time period the Roman Stoic philosopher,Seneca, described actual magnification by a globe of water. "Letters, however small and indistinct, are seen enlarged and more clearly through a globe of glass filled with water." This particular manner of observing things was not utilized much until the end of the 13th century…

The Fresnel lens was first invented by French physicist Augustine Fresnel and at first were a simple, beehive resembling contraption with a light source in the middle, but then it developed into something that mirrored a bull’s eye with a more powerful beam (Fresnel Lenses). The Michigan Lighthouse Conservancy went on to explain that the Fresnel lens was created for the sole purpose of installation within lighthouses. The efficiency and power of a Fresnel lens allowed its design to emit a source…

xylinus. Data represented in Fig 4.14 exhibited the surface view for biocellulose under 15000 × magnification nanofiberils which can’t be observed due to converge by a thick layers so it has well interconnected pore network structure and biocellulose dried sheet under 10000× magnification, the biocellulose was fibrous with irregular size and shape (Fig 4.15). Observation of biocellulose under 10000 × magnification showed the fine cellulose ribbons, sometimes called fibrils. Observation of…

Abstract. In this work investigation for the effect of compressed CO2 on the morphology of the produced Polyaniline (PANI) was carried out. The conventional oxidative polymerization using ammonium peroxydisulfate as oxidizing agent was used with and without compressed CO2. The results showed that different morphologies of PANI nanorods and PANI nanoparticles were produced using the conventional polymerization with and without compressed CO2 respectively. Molecular characterization of the…

During this lab, Sfr13 mutant and wild type Tetrahymena’s number of India Ink vacuoles and sizes were observed over multiple trials, and then the averages were compared to see if there was any difference between the mutant and WT. Furthermore, the two strains of Tetrahymena were stained with mCherry fluorescence, so that the oral grooves could be examined and compared under fluorescence microscopy. This experiment was designed to eliminate as much bias as possible by replicating the experiment…

prior to the lab: one tested on Friday, four died over the weekend, four were used on Monday, and three on Tuesday. The eggs were collected from the previous class’s one female out the four used. The eggs were observed on a microscope at 10X magnification. We were instructed to gather information on: size, shape, estimate of amount of eggs in solution. We were also going to place the eggs into sumi ink; however, we did not place the eggs within the ink. Individually we did not do this task,…
